Is the muezzin's statement aloud after the Adhan, "O first and best of Allah's creation," sound?

The wordings of the Adhan are restricted, and adding a permanent addition not established in the Sharia is an innovation (bid'ah). supplicating the Prophet with phrases like "O best of creation" or "O first of creation" for seeking aid (istighathah) is forbidden by Islamic law because istighathah is due only to Allah Almighty. The Prophet said: "Aid is not sought from me; rather, aid is sought from Allah." Intercession using the phrase "by the right of the Prophet" is a matter of dispute, and the preponderant opinion is that it is forbidden. The claim that the Prophet is the first of creation is false.
